I guess the 15-month-old was crying too loudly, or didn't want to take a nap, something like that -- so the daycare worker took care of it. SMH.
Why didn't the worker just walk away or ask for help?
Now this little one is fighting for her/his life. The child's parents must be crying, praying, and screaming all at the same time.
Hoping for good news. Be strong, Little One.
